JOHN H. CONN, OF ENGLEWOOD, ILLINOIS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 369,775, datedSeptember 13 1887. Application filed July 2, 1887. Serial No. 243.234.(No model.)

To all whom it may concern:

Be it known that I, JOHN H. CQNN, a citi: zen of the United States,'residing at Englewood, in the county of Oook and State of Illinois,have invented a new and useful Improve ment in Car-Oouplings, of whicht-he following is a specification.

Myinvention relates to improvements in earcouplings; and it consists incertain novel features hereinafter describedand claimed.

In the accompanying drawings, whiohfully illustrate my invention, Figurel is a vertical longitudinal section showing two draw-heads Fig. 2 is anend view of one ofthe draw-heads. Fig. 3 is a longitudinal section ofone of the drawheads, showing the pin in its uncoupled position. Fig. 4is a detail perspective view of the coupling-pin, and Fig. 5 is a detailperspective View ot' the tumbler.

Referring to the drawings by letter, A designates the draw-head securedto the under side ofthe car, at the end ot' the same, in the usual orany preferred manner. The upper side or top ot' the drawhead is cut awayfor the insertion of the tumbler, and thespace thus formed is coveredand closed by a plate, B, having a slot, O, at its forward end, throughwhich the coupling-pin works. A tumbler, D, is hung in the draw-headjust in rear of the slot in which the coupling-pin works, and has theforwardly-extending front face, E, which projects normally in the pathof the pin and has the shoulder or ridge F across its upper end. Thefrontend of the draw-head is closed, and is provided near its lower edgewith a transverse slot, G, ot' sufficient width to admit the end of thecoupling-link. The coupling-pin H is provided on its rear side with atransverseshoulder, I, which engages the shoulder F ofthe tumbler, asclearly shown in Fig. 3, and thereby supports the pin'iu position todrop into engagement with the link. The upper end of the pin isconnected by a link, J, to a crankshaft, K, journaled on the end of thecar andiV extending to the side of the same, so thatthe device can beuncoupled without going between the ears.

L is a rod connected to the crank-shaftK and extending to the top of thecar, so that the device may be operated from that poi'nt,if so desired.

The operation of my device will be readily understood. The link issecured in one drawhead and the draw-heads brought together. The freeend of the link entering the uncoupled draw head will push the tumblerbackward, thereby releasing the pin, which instantly drops intoengagement with the link, as will be understood. To uncouple,it isnecessary only to release the pin in one drawhead from thelink,when thelink willbe drawn out ol" the draw-head and the tumbler willautomatically swing forward into position to support the pin.

It will be observed that the device is very simple and is entirelyautomatic in its opera tion, thus dispensing with the necessity of thebrakeman Agoing between the cars and endangering life and limb.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

` l l. The combination of the draw-head having its front end closed andprovided with a transverse slot, G, in its lower portion, the tumblerpivotally supported in the draw-head, the link entering the draw-headthrough the slot G, and the pin supported by the tumbler and adapted toengage the link, substantially as set forth.

2. The combination of the draw-head having its interior cut away orrecessed, the tunibler hung in said recessed portion, the plate B,covering the same, and having a slot, O, near its front end, and the pinpassing through said slot O and supported bythetunibler, substantiallyas specitied.`

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
